The SR is not electrically insulated. Death or
serious injury can result from contact with, or
inadequate clearance from, an energised
conductor. Do not go closer than the minimum
safe approach distance as defined by ANSI.

n Pre-start Inspection
At the start of each work shift, the SR3370 /
SR2770 shall be given a vi
sual in
spec
tion and
func tion test. See the Daily In spec tion and Main te -
nance chap ter , in this man ual for a list of items to
in spect and test.
DO NOT operate the SR3370 / SR2770 unless
you are trained and authorized, understand the
operation characteristics of the SR3370 /
SR2770, and have inspected and tested all
functions to be sure they are in proper working
order.
